Your tropical fish needs a nutritious diet to stay healthy, so for best results it is recommended that they receive two feedings of balanced meals every day. When selecting food with multiple essential nutrients and softening pellets prior to use.

Tropical Fish Food

Goldfish and tropical fish species can eat similar foods, yet feeding your goldfish these items regularly could prove detrimental to its wellbeing. This is because tropical fish food typically contains different proportions of essential vitamins than their natural diet does, leading to deficiencies. Over time this could leave your pet lacking essential nutrition.

Goldfish fish naturally consume aquatic plants, insects, shrimp and other organisms with protein-rich diets; however, most tropical fish flakes available on the market today focus heavily on proteins rather than providing essential fiber that goldfish need for proper survival.

At home aquariums, many tropical fish we keep are top feeders that primarily consume floating food like goldfish flakes. Unfortunately, too much air intake may cause or exacerbate swim bladder issues; therefore it’s wiser to give your goldfish only small doses of tropical fish flakes; for optimal results try feeding your goldfish vegetables like peas, chopped lettuce or cucumber instead of flaked food.


Goldfish will consume food designed for tropical fish, but this does not meet their long term dietary needs. Goldfish are generally bottom feeders and require higher protein-based foods than those designed for tropical species.

Vegetables provide goldfish with essential vitamins and nutrients. If possible, choose canned green beans, canned zucchini slices and cooked garden peas (with shell removed), which should all make excellent choices for diets. If a vegetable is too hard for nibbling on, blanch it before giving to your goldfish.

Frozen vegetables make an excellent addition to a goldfish diet, such as kale, collard greens, spinach and romaine lettuce. Some owners also feed their goldfish sliced pieces of fresh carrots that should be lightly steamed before feeding to them. A varied diet helps prevent bloat, constipation and color loss while improving aquarium water conditions overall.


Tropical fish require a diet rich in variety to remain healthy, retain vibrant colors, and avoid digestive issues like bloat. By including fruits in their regular feeding schedules, tropical fish can boost antioxidant levels that provide important health benefits to their immune systems.

Fruits that are safe for goldfish include bananas, plantains, peas, pumpkins, apples, pears and carrots – these should all be chopped into small pieces before feeding to your fish.

Occasional tropical fish flakes (which they will tolerate) is fine; however, goldfish do not possess stomachs to properly break down processed food for absorption into their bodies, and thus will expel poorly digested waste into the tank, potentially leading to bacterial blooms and dirty water conditions.
